A ilioatlon filed July 1911. Serial No. 336637.

herein explained and the best mode in which I have contemplated applyingthat principie, so as to distinguish it iroin other inventrons.

he present invention is concerned more particularly With glass baits theype shown and described in United. States Pet ent No. 972,615, grantedme October 11, 1916. i

The object of the invention is to provide a simple and exp-ed iousmethod, and appsretus for use therein, whereby the residue of glassadhering to such bait may be re moved therefrom.

The buit in question, is clmmcterized by the use of a flexible metallicbend or ribbon for the bait member proper, which comes in contact withthe both of molten gloss, and to which the upper end ol the cylinder andhorse duringthe drawing operation. After the cylinder is severed, therewill still remain at least a coating of glass on such ble bait member.This, it has been found,

must be thoroughly and com Jletely removed before the drawing operationcan be repented in other words, the proper adhesive and cohesiveconnection oi the of the cylinder with the bait member, up}? entlyconditional u 011 such member ol'esen u p l is bright, clean, metallicsurrace,

The present invention consists of the steps and means hereinafter fullydescribed and particularly pointed out in the claims,

The annexed drawing and the following description set forth in detailcertain means ,and one mode of carrying out the invention, suchdisclosed means and mode illustrating, however, but one oi -various waysin which the principle of the invention in y be used. 'lln seidennexeddruwingz-Ji ure 1 is a. plan view of one approved construction ofapparatus for use lIl connection with the present v improved method ofcleaning; baits; :zlFig.

The general method of procedure involved, it may be preliminarilyexplained, consists in chillin the gloss and the bait member, to whichit odheres, thereupon flexing such bait member, and then brushing themember to frictionelly remove any remaining particles of the the purposeof thus chilling the glass and belt member, I preferably employ a pan 1,

of metal or other like material F i .1 in

which a false, perforated ported some distance above the floor or bottomproper, ot' the pan. The water or equivalent cooling medium enters thepan by an inlet pipe 3, and is discharged therefrom by an outlet pipe42, so arranged (see Fig. 2} as to inaint I in the pan. is indicated,the level of the writer: such as to entirely submerge the false bottom2, a depth of approximately one-fourth inch of Water above such bottombeing desirable. is gag-ed to only partially submerge-the ribbons 5 thatform the bait members proper oi' the buit 6. shown. as restingin thechilling pen in llifgs'l and 2. I

in the modified form of construction illustrated in F 3, in addition tosuch false bottom pa IO rated plute'2, I employ a bed 7 of sbestos,placing the some upon such bottom, thickness substantially equal to, orthan the level of water maintained 1c pan, The glass bait 6, to bechilled, being removed from, their carriers or supports in the ,gglussdrawing machine, the cylini" or rollers in QEtQll case beingsewierefrom, ere immediately placed in the pan, with the lower edge of theflexible bait member 5, proper, resting upon the peri'iorf l plate orbibulous mat. By reuthe action of the Water, or coolin son of bottom 2is sup-.

This depth, in other words,"

or other bibulous masorrelinclin or in Contact with the 9 h b-iit memberin the eonstructional form of i i ,s. l '2, or by reason of the chillingaction produced by the rising vapor and the contact of the glass or edgeof the bait member with the asbestos or bibulous mat in the form ofconstruction illustrated in'Fig. 3,

in this Way. Thereupon I remove the bait from the pan, and place it withthe aforesaid flexible bait member resting on an anvil 8 having aconcave surface of a curvature less than that of said member, as shownin Fig. i; then by lightly tapping the ribbon-like member with a hammer9 or like implement, successive blows being delivered at successivepoints as the bait member is rotated across the anvil, any remainingfragments of'glass adhering or fastened to the bait member are broken-loose and disengaged therefrom by the flexure of the member thusproduced.

It is to be understood that the bait member should not be subjectedtoany pounding or bending, such as would permanently distort it; thebending, on the contrary, is desirably kept within the elastic limits ofthe material composing said member. Only a relatively limited section ofthe bait member, furthermore, is flexed at any one time, whichever typeof flexing device is employed. In lieu of thus tapping the member inorder to produce this flexure, and thereby detaching the remainingfragments of glass, a device in the form of a tongs or pliers 10, asillustrated in Fig. 5, may be employed. In such event, the use of ananvil is dispensed with, since the pliers are constructed to engage bothsides of the bait, so thatby simplv closing the handles, the slightflexure of the bait member, which is required to free the particles ofglass therefrom, is secured. After having flexed the bait member in thefashion just described, it may be found advisable under certainconditions, to brush the same with a stiff wire brush, or to apply asand-blast thereto, in order to insure the complete removal of anyremaining particles of glass that cling thereto. By this concludingoperation, moreover, any oxid that may have formed about the line ofcontact of the glass with the metal of said bait member is removed.

By the foregoing several steps, constituting my improved method, thesurface of the metal ribbon, forming the flexible bait member, will beleft perfectly clear and clean, and will not show any discoloration byreason of absorbed oxid, so that the glass may firmly adhere or attachitself I shall term adherence, because there is invariably formed astratum of oxid of the metal between the glass and the pure metal of thetool. This oxid, I assume, is formed incidentally to the pre-heating ofthe tool, which is always necessary with tools of this class.

In the caseof bait members of the class herein referred to, on thecontrary, such members consisting" of a relatively thin, flexible bandor ribbon of metal, the crosssection or volume of the member is such asto permit said member to be heated, to a point where the glass willunite with it, by the contained heat of the glass, without anypre-heating whatever. The union thus obtained between glass and bait, ismaterially different from the adhesion previously discussed, and, todistinguish therefrom, may be termed cohesion, The surface of the metal,in the case of such cohesion, remains perfectly clear and clean and doesnot show any of the discoloration produced by absorbed oxid.

It is more particularly to meet the difliculties of properly cleaningthe bait, that are presented by this condition, that the presentimproved method and apparatus have been devised; although it is notmeant by this, to imply that such use will constitute the only field forapplication of the invention.

Other modes of applying the principle of my invention may be employedinstead of the one explained, change being made as regards the means andthe steps herein dis'-' closed, provided those stated by any one of thefollowing claims or their equivalents be employed.

I therefore particularly point out and distinctly claim as myinvention 1. The method of cleaning glass-baits of the class described,which consists in chill- ;ing the bait member, proper; then flexing thesame; and finally subjecting said memher to friction, whereby thecontacting surface thereof is not only cleansed of adhering glass butalso left bright and clear of oxid, substantially as described.

2. The method of cleaning glass-baits of the class described, whichconsists in chilling the bait member, proper, by dipping the same in acooling liquid; then flexing said member in small sections at a time soas to avoid distorting the same; and finally subjecting said member tofriction; whereby the contacting surface thereof is not only cleansed ofadhering glass but also left bright and clear '01 oxid, substantially asdescribed.

3. The method of cleaning glass baits of the class described whichconsists in im- 0 Incl-sing the bait member in a cooling liquid Signedby me this 28th day of June, 1911. 15
